Ii-ether ze-celluloseIngakumbi ii-ether ze-hypromellose, zizinto ezibalulekileyo kwiimortar zorhwebo. Kwi-cellulose ether, i-viscosity yayo luphawu olubalulekileyo lwamashishini okuvelisa i-mortar, i-viscosity ephezulu sele iphantse yaba yimfuno esisiseko kushishino lwe-mortar. Ngenxa yempembelelo yetekhnoloji, inkqubo kunye nezixhobo, kunzima ukuqinisekisa i-viscosity ephezulu yasekhaya.i-cellulose etheriimveliso ixesha elide. I-Cellulose ether isetyenziswa njengearhente yokugcina amanzi, i-thickener kunye ne-binder kwiimveliso ze-mortar, enefuthe elikhulu ekusebenzeni, i-viscosity emanzi, ixesha lokusebenza kunye nendlela yokwakha yenkqubo ye-mortar. Le misebenzi ifezekiswa ikakhulu yi-hydrogen bond phakathi kwe-molecule ye-cellulose ether kunye ne-molecule yamanzi kunye nesenzo sokujika kwe-molecule ye-cellulose ether, eneneni, ithatha inxalenye ye-hydrogen bond kwi-cellulose ether molecular chain kwaye ibuthathaka ukuxinana kwe-cellulose ether, nto leyo ebuthathaka ukugcinwa kwamanzi kunye nokukwazi ukumanzisa kwe-cellulose ether. Abavelisi be-mortar uninzi lwabo abazivanga eli nqaku, kwelinye icala, iimveliso ze-mortar zasekhaya zisenzima, azikaqapheli ukuba zinike ingqalelo kwinqanaba lokusebenza, kwelinye icala, sikhetha i-viscosity ephezulu kakhulu kune-viscosity efunekayo yobugcisa, le nxalenye ikwahlawulela ukulahleka kokugcinwa kwamanzi, kodwa kwi-wettability yonakele.
Ukusebenza kwe-mortar kuchatshazelwa yi-cellulose ether equlethe i-adhesive extractant kwinkqubo yokuvelisa, kweli phepha, umahluko phakathi kwamandla e-tensile adhesive phakathi kwemveliso ye-cellulose kunye nemveliso ye-cellulose ether eyongezwe nge-tackifier kwi-ceramic tile adhesive iqinisekiswe ziimvavanyo. I-Tackifier luhlobo lwezinto ezongezwe ngabanye abavelisi be-cellulose ether ukuze bahlawulele ukunqongophala kwetekhnoloji yemveliso, itekhnoloji kunye nezixhobo. Ubukho be-tackifier benza iimolekyuli ze-long chain ze-cellulose ether cross-link kwaye zibe yi-net-like, nto leyo echaphazela isantya sokwenziwa kwefilimu ye-cellulose ether kunye nemeko yefilimu, ngaloo ndlela ichaphazela indima ye-cellulose ether kwi-mortar, impembelelo yokujonga ngqo yile: amandla e-tensile adhesive atshintshile phantsi kwemeko nganye yokuphilisa; ixesha lokuseta le-mortar liyanda.
1. Phantsi kwemeko eqhelekileyo yokunyanga, ukongezwa kwe-tackifier kunye ne-cellulose ether ngaphandle kwe-tackifier kwinkqubo yemveliso kunempembelelo ethile kumandla okunamathela okuthambileyo kwe-ceramic tile adhesive, iimveliso ezongezwe nge-tackifier kwinkqubo yemveliso zinamandla okunamathela aphezulu okunamathela.
2. Kwicala lokumelana namanzi, amandla okunamathela okutyhafayo kwe-ceramic tile adhesive ene-cellulose ether eyongeziweyo kwi-tackifier kwinkqubo yemveliso mabi kunalawo emveliso ngaphandle kwe-tackifier kwinkqubo yesiqhelo yemveliso, i-cellulose ether equlethe i-tackifier ichaphazela ukumelana namanzi kwe-tile adhesive.
3. Ngokuphathelele ixesha lokubeka umoya,i-cellulose etherkunye ne-tackifier yayisetyenziswa kwi-adhesive yethayile, amandla ayo okunamathela okuthambileyo ayephantsi kunalawo emveliso ngaphandle kwe-tackifier, kwaye ixesha lokuvula lafinyezwa.
4. Ngokuphathelele ixesha lokuseta, isantya sokunyanga se-cellulose ether ceramic tile adhesive ngaphandle kokongeza i-tackifier phantsi kwenkqubo yemveliso eqhelekileyo sikhawuleza. Ngamafutshane, ubukho be-tackifier, isenzo sokuhlanganisa esenza isisombululo samanzi se-cellulose ether sibe nomqobo ophezulu we-steric, obonakaliswe ukuba uphezulu kuvavanyo, kodwa ubukho be-tackifier buchaphazela iipropati ezininzi ezibalulekileyo zokusetyenziswa kwe-cellulose ether, njengokumelana namanzi, ixesha lokuvula, ukumanzi njalo njalo. Enyanisweni, i-viscosity yenye yee-index zokusebenza ze-cellulose ether, i-viscosity ayisiyo i-index ebalulekileyo yokusebenza okubanzi kwe-cellulose ether, kodwa uhlobo kunye nomxholo wamaqela kufuneka kube yeyona nto iphambili kubavelisi be-mortar.
5. Kungenxa yokuba abavelisi be-mortar banikela ingqalelo kakhulu kwi-viscosity, nto leyo ebangela ukuba amanye amashishini emveliso ye-cellulose ether andise i-viscosity ngokusebenzisa izixhobo ezongezelelweyo ukuhlangabezana neemfuno zabavelisi be-mortar, kwaye olu hlobo lweemveliso lune-viscosity ebonakalayo ephezulu kuphela, ukusebenza kwayo okubanzi kufanelekile ukuba kuqwalaselwe ngabasebenzisi, kwaye i-viscosity ebonakalayo ephezulu eyenziwe yi-viscosity ekhulayo ayinakufezekisa ithiyori ethi "i-viscosity ephezulu engaphantsi komxholo" elindelwe ngabavelisi be-mortar, kodwa ayikho ngokwenene. Ukuze kukhethwe i-cellulose ether, eyimpahla ebalulekileyo eluhlaza kwi-mortar, amashishini e-mortar alandela umgangatho ophezulu nozinzileyo kufuneka azi ulwazi oluthile olungasemva, oku kuya kuba luncedo kubavelisi ukuba baphuhlise iimveliso ezisebenza kakuhle, ukuqinisekisa uzinzo lomgangatho wemveliso.
